Kim Kardashian will reportedly be a mother of four.
Us Weekly said Kardashian and West are having a baby boy. Sources said the couple's gestational carrier is due to give birth in early May.
Kardashian and West are already parents to 5-year-old daughter North, 3-year-old son Saint and 11-month-old daughter Chicago.
The couple welcomed Chicago via surrogate in January 2018.
Kardashian had discussed the possibility of baby No. 4 with E! News in August, but denied she was expecting at the time.
She previously told Elle a fourth child would be her last.
"I don't think I could handle more than [four]," she said.
"My time is spread really thin. And I think it's important that in all couples, the mom gives the husband as much attention as the kids."
Kardashian shared photos with West and their three kids last week after hosting her family's annual Christmas Eve party.
North wore a shade of red lipstick to the bash that Kardashian later hinted will be a KKW Beauty release.
